Heat's McCullum to call time on BBL career

Brisbane Heat foundation star Brendon McCullum is calling time on his Big Bash League career as the New Zealand veteran transitions into cricket's coaching ranks.

Friday's season-ending clash for the Heat against the Melbourne Stars will be the 37-year-old's last appearance in the BBL after he decided to retire from Australia's domestic Twenty20 competition.

"I will continue to play T20 cricket in 2019 in various competitions around the world and will then look to transition into a coaching career," McCullum told teammates in the aftermath of their six-wicket win over Adelaide on Sunday night.
